Definitions

  • the invention relates to a conveyor for meat, bone and. Like., With a screw conveyor and a channel-like housing that encompasses this from below, on the housing part of which is circular in cross-section, a channel wall adjoins on both sides. Conveyor devices of this type are already known per se, and they are used in many branches of industry, in particular in the meat processing industry, in a wide variety of sizes and designs. In particular they are used to transport the goods to be processed from one station to the next.
  • the housing part which is circular in cross-section, encloses the conveyor screw along an angle of 180 °.
  • the channel walls run parallel to one another, their lateral spacing corresponding to the diameter of the housing part which is circular in cross section. As a result, these channel walls run at an acute angle to the screw flights. If a bone splinter now gets into this narrow gap between the inlet-side channel wall and a screw flight, there is a risk that the screw conveyor will pull it into this narrowing gap, and this can lead to the screw conveyor being blocked. Apart from the interruption of the conveying process, damage to the conveying device and / or its drive can occur.
  • the object of the invention is therefore to provide a conveyor device of the type mentioned, in which such blocking by bone fragments u. Like. Avoided or at least less likely.
  • a conveyor device according to the preamble of claim 1 is proposed, which is designed according to the invention in accordance with the characterizing part of the first claim.
  • the shoulder-like chest surface runs in the radial or approximately radial direction to an imaginary cylinder enveloping the screw conveyor.
  • the flights of the screw conveyor or an imaginary tangential surface to the screw conveyor in the area of the inner end of the chest surface it includes a substantially larger, in particular obtuse, angle than the known prior art.
  • Their width, in the radial or approximately radial direction to the screw conveyor seen, is to be chosen so that the largest usually occurring bone fragments can be easily accommodated. Due to the vibrations, which are inevitable during the operation of such devices, the bone splinter is moved in the conveying direction or due to gravity with a corresponding inclination of the conveying device against the conveying direction, and it then falls between two screw flights in the cross-sectionally circular housing part, where it then together with the meat or any other goods to be transported.
  • the chest surface is located on the inlet side of the housing.
  • the “inlet side” is understood to mean the long side of the housing on which the screw flights, coming from above, are immersed. It is not to be confused with the inlet of the conveyor at which the latter is fed the goods.
  • the chest surface is inclined towards the screw conveyor, so that the bone fragments and the like which have got there. can slip due to their own weight between two snails in the cross-sectionally circular housing part.
  • the latter encloses the screw conveyor on its or each side facing the breast surface beyond the horizontal.
  • the breast surfaces and the part of the housing which is circular in cross-section and extends beyond the horizontal line form a kind of wedge.
  • the advantage of this design is that the overall width of the housing does not widen across the conveying direction compared to the conventional design. As a result, it is easily possible to improve already existing conveying devices in the manner according to the invention if the wiping wedge mentioned is manufactured separately and installed at the appropriate point.
  • the section of the housing which is above the horizontal and has a circular cross section, extends preferably over an angle of approximately 30 ° to 60 °.
  • an imaginary extension of the breast surface be located above the geometric axis of the screw conveyor.
  • the distance should not be too big, however, so that the chest area receives a sufficiently steep gradient.
  • the latter and the section of the housing which is circular in cross-section and above the horizontal form an angle of approximately 90 °.
  • the conveyor device has a channel-like housing 1, which comprises the screw conveyor 2 from below. It consists of a housing part 3 which is circular in cross-section and to which a channel wall 4 or 5 is connected on both sides. The free ends of the latter can, for example, at right angles are bent outside, so that support surfaces 6 and 7 arise for a cover, not shown.
  • the channel wall 4 merges tangentially into the housing part 3 which is circular in cross section.
  • the housing part which is circular in cross-section is continued beyond the horizontal 8, the part of the housing which is above the horizontal and of course also in the cross section being designated by 9 in cross section. It extends over an angle 10 of approximately 45 ° and is located in the direction of arrow 11 on the inlet side 12 of the housing 1 when the screw conveyor 2 is rotating.
  • a so-called breast surface 13 adjoins the section 9 of the housing 1 which is circular in cross-section and is located above the horizontal 8.
  • These two housing parts and the housing wall 5 adjoining at the top together form a step-like part of the housing 1.
  • the housing parts 9 and 13 together form a wiping wedge 14.
  • the chest surface 13 preferably does not run exactly in the radial direction, rather an imaginary one goes inwards extension of the Breast surface above the geometric axis 15 of the screw conveyor 2 past.
  • the chest surface and the housing section 9 form an angle 16 of preferably approximately 90 ° with one another.
  • the channel wall 5 not only runs parallel to the channel wall 4, but also at the same lateral distance from an imaginary vertical plane 17.
  • the housing part 3, which is circular in cross-section, and the two channel walls 4 and 5 are preferably manufactured in one piece together with the housing part 9 and the chest surface 13 and the support surfaces 6 and 7.
  • the channel wall 5 is connected in an analogous manner to the channel wall 4 directly to the housing part 3, which is circular in cross-section, and the wiper wedge 14 is manufactured separately and attached to it at the appropriate point.
  • a wider housing 1 would be obtained if the channel wall 5 were aligned vertically.
  • the construction drawn represents the preferred embodiment of the invention.
  • the inclined from the top outside downward inside chest surface 13 encloses an obtuse angle 18 with the imaginary cylinder 17 around the screw conveyor 2 or a tangential surface placed at its inner end on this cylinder, while the corresponding angle 19 on the opposite channel wall 4 is acute is.
  • the housing 1 preferably in the form of an inlet funnel, and the outlet at the other end.
  • the housing 1 is closed at the end, for example with a flat plate, which is not shown in the drawing, however.
